LAWRENCE 1\T. BROOKS, OF CHAMBERLAIN, SQU'IH DAKOTA,

GREASE-GUN ATTACHMENT.

Application filed December 18, 1923.

To all whom it m concern Be it known that I, LAWRENCE N. Bnoons,

a citizen of the United States, residing at Chamberlain, in the county of Brule and 5 State of South Dakota, have invented certain new and useful Improvements in Grease-Gun Attachments, of which the following is a specification.

This invention relates generally to grease guns and has more particular reference to an attachment therefor, whereby the bearings of vehicle wheels may be advantageously and quickly greased, the primary object of the invention residing in the provision of such an attachment that may be manufactured and marketed at a. relatively small cost and one that may be associated with practically all types of grease guns now upon the market.

\Vith the above and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts of a grease gun attachment hereinafter 25 more fully described, shown in theaccompanying drawings and claimed.

In the drawing wherein there is disclosed the most practical embodiment of the invention with which I am at this time. familiar: the figure is a longitudinal sectional view of a grease gun attachment constructed in accordance with the present invention.

Now having particular reference to the drawing, my novel attachment for grease guns embodies the provision of a metal cup 5 that is open at its opposite ends, the enlarged open end of said cup terminating in a horizontal portion 6 that is internally screw-threaded as at 7. The contracted open end of said cup is swivelly connected as at 8 to one end of a nipple 9 that is formed with a longitudinal passage, the in ner end of which is relatively enlarged and screw-threaded for the reception of the usual screw-threaded outlet nipple 10 of a well known form of cut-off cook 11. To the inlet nipple of this cock, there is connected as at 12, one end of afiexible hose 13, the other end thereof being connected to the outlet of the grease gun, not shown.

Serial No. 681,428.

The cup 5 is provided with a plurality of right angularly extendlg operating knobs l4, and in actual practice,

the hub caps of the vehicle wheels are removed after which the cock 5 is engaged with the hub of the wheel, and whereby after the pet cock has invention.

It will thus be seen that I have provided a highly novel and useful form of grease gun attachment whereby wheel bearings may be etfectively and easily lubricant.

supplied with I have shown in the drawing and set forth 1 I I a i 111 tne specification, a particular form of grease gun attachment, but it is nevertheless to be understood, that minor changes be made in from the spirit claims.

may the lnvention withoutdeparting and scope of the appended Having thusdescribed my invention, what I claim as new and deslre to secure by Letters Patent 1. In an cut-off valve,

is attachment for grease guns, a a cup shaped member swivelly connected to the outlet nipple of said valve and being internally screw-threaded at its opposite end whereby the same may sitioned upon the hub of a vehicle he powheel.

and means at the inlet nipple of said valve for attachment to a grease gun for the purposes described.

2. In an cut-olf cock attachment for grease guns. :1 a conical shaped cup member swivelly connected to the outlet nipple of the cock and being formed end with t at its opposite internal screw-threads, handle members carried by said cup whereby the same may be readily positioned rpon the hub of a vehicle wheel, and a flexible hose connected at one end to the inlet nipple of sand cock and adapted to be connected at lts opposite end to the outlet of said rease 1111.

In testimony whereof I allix my signature.
